Maintaining Your Detention Basin: a Guidebook for Private Owners in Clermont County
Maintaining Your Detention Basin: A Guidebook for Private Owners in Clermont County A well maintained detention basin BASINS Your detention basin is a storm water best management practice (BMP) designed to tempo- INTRODUCTION rarily capture and hold storm water runoff during periods of heavy rain, and slowly release this flow over a period of one or two days so it minimizes flooding and streambank erosion problems downstream. They also help remove sediments from storm water runoff, which helps improve the quality of local streams. Like most other things, a detention basin may not function properly or it may fail prematurely if not properly maintained. Once a detention basin fails, it is often very expensive to correct. Many detention basins are located on private property, including parcels of land owned and maintained by a homeowners association (HOA). Local governments do not have the au- thority to maintain components of the storm sewer system on private property, including detention basins. Rather, these are the responsibility of the lot owner to maintain. Whether you are an individual property owner, a homeowner’s association representative, or a residential/commercial property manager, this Guidebook will help answer questions and provide you with instructions for basin maintenance activities. Routine maintenance will prolong the life of your detention basin, improve its appearance, help prevent flooding and property damage, and enhance local streams and lakes. WHAT ARE DETENTION BASINS AND WHY ARE THEY IMPORTANT? When land is altered to build homes and other developments, the natural system of trees and plants over relatively spongy soil is replaced with harder surfaces like sidewalks, streets, decks, roofs, driveways and even lawns over compacted soils. -
Single Family Residential Stormwater Management Plan Dry Well (Infiltration) Construction Inspections
Single Family Residential Stormwater Management Plan DRY WELL (INFILTRATION) Definition : A dry well is an excavated pit filled with gravel and sand that provides temporary storage of runoff from roofs and allows for infiltration of that runoff over a 48 hour period. Constraints : • Dry wells should not be used in areas where their operation may create a risk for basement flooding, interfere with septic sewage disposal systems, or cause downslope seepage problems • May not be installed on slopes greater than 20% • Drainage area to each dry well shall not exceed 1000 square feet • Dry wells may not be used in HSG D or if the infiltration rate of the soil is less than 0.27 inches per hour • Dry wells are intended to capture rooftop runoff only Design Guidance: • Dry wells must be installed in accordance with the attached detail • Dry wells should not intercept water table, bedrock, fragipan or other confining layer • Dry wells must be located down gradient of building structures and set back at least 10 feet from buildings, 50 feet from water supply wells and 25 feet from septic systems • Dry wells must be set back at least 50 feet from fill slopes of 25% or steeper • Soils will be evaluated during excavation by ASCD representative to evaluate soil suitability assumed in original design which may alter type of practice to be constructed Installation: • Minimize compaction of dry well bottom and sidewalls • Collection pipes from downspouts shall be 4”-6” PVC installed at min. slope of 1% • The bottom of the dry well excavation should be -

Chapter 23: Detention Basin Standards
CHAPTER 23: DETENTION BASIN STANDARDS 23.00 Introduction and Goals 23.01 Administration 23.02 Standards 23.03 Standard Attachments 23.1 City of Champaign Manual of Practice March 2002 Chapter 23: Detention Basin Standards 23.00 INTRODUCTION AND GOALS A. The purpose of this chapter is to explain the City’s policy regarding the ownership, design, construction, and maintenance responsibility for detention basins. Detention basins are used to collect and hold stormwater runoff for a period of time to compensate for increases in stormwater runoff caused by reduced ground surface perviousness due to activities such as paving or building construction. B. Detention basins historically range in size from backyard detention provided by swales, to large regional detention ponds. Detention basins may be wet or dry bottomed. Residential backyard or sideyard single lot detention is not allowed. Construction of detention for individual lots of less than 5 acres is not recommended; alternate methods such as payment in lieu of detention or one basin for the entire subdivision or development are preferred. 23.01 ADMINISTRATION A. This chapter applies to detention basins within the City limits and the 1-1/2 mile extra territorial jurisdiction. B. Detention basin construction is required for certain conditions by the City of Champaign Stormwater Management Regulations. C. Detention basin design shall be reviewed by the City of Champaign through either of the following: 1. Subdivision plan review 2. Grading and drainage plan review 3. Alternate construction plan review (typically public improvements) 23.02 STANDARDS The following standards apply to detention basins: A. Referenced Standards: Design standards for detention basin design and construction shall comply with the provisions of the following, unless otherwise stated by this manual. -
